ADS8482 - 18 Bit 1MSPS Parallel ADC W/Ref, Pseudo Bipolar, Fully Differential Input

The ADS8482 is an 18-bit, 1-MSPS A/C converter with an internal 4.096-V reference and a pseudo-bipolar, fully differential input. The device includes a 18-bit capacitor-based SAR A/D converter with inherent sample and hold. The ADS8482 offers a full 18-bit interface, a 16-bit option where data is read using two read cycles, or an 8-bit bus option using three read cycles.

The ADS8482 is available in a 48-lead 7x7 QFN package and is characterized over the industrial -40°C to 85°C temperature range.
